SAMSUNG DLP

our toshiba 42" projection tv broke after 2yrs. accdg to inhome svc guy from bestbuy, samsung is the best brand for tvs. dlp vs lcd/plasma? he recommended dlp. so we got samsung 50" dlp (did not bother looking at reviews). we are happy with it but seems it's showing some pixels. but when we change channel to hd, sometimes it shows great pictures. sometimes delayed images. we are confused if it's the tv or poor reception from time warner. we already asked for t.w. service -- but at that time, all channels were showing great pictures. help! is samsung really a grood brand?

I need help, too! Does anyone know of any brick and mortar stores to buy lamps for DLP's? I live in Dallas if that helps, just don't want to have to spend a rainy weekend with kids and no TV (how did people live without it??) and don't want to have to pay $72 for Saturday delivery...

I bought a Samsung HLS5 in March '07 and was getting a highly superior HD picture. But now, just about three months after purchase, I'm getting pixellation in between areas of different color. Kinda looks like a 'border' around these areas, and it's driving me to drink. I've lost the sharp, wonderful DLP picture that I had!

Thank heaven it's still under warranty, but has anyone else seen this phenomena? If so, do you know what's causing it?

It does this all the time, no matter what the source is (DVD, cable, PC).
